What risks did Sacajawea take?

1 risk Sacagawea had to take in order for her to become a member of the expedition was strap her baby boy to her back and travel with him. reason number 2 is she had to make sure she was not sick because getting sick on the boat would mean more time to succeed in the trip. Although she did not make sure she was healthy because she ended up being very sick, Lewis and Clark had to take care of her in a small tent on the boat. A 3rd reason is, she had to say good bye to her husband. Although he was 40 years old and she was a teen.
